First, the product is a good solvent for many organic compounds, combined with carbon disulfide, can dissolve proteins. It is also an excellent solvent for organic reactions. Results that are difficult to obtain in general organic solvents can be obtained.
Second, trifluoroacetic acid is an important reagent for organic synthesis, by which it can synthesize various fluorinated compounds, pesticides and dyes. Trifluoroacetic acid is also a catalyst for esterification and condensation reactions; It can also be used as a protective agent for hydroxyl and amino groups for the synthesis of sugars and peptides.
Third, trifluoroacetic acid (TFA) is a commonly used organic acid in chemical laboratories, because the carboxyl group ortho-carbon is connected with 3 relatively strong electronegative group fluorine atoms, so the nucleophility of carboxylate is greatly reduced, so trifluoroacetic acid is often used as a solvent to study the solvent effect of the reaction. Trifluoroacetic acid has a relatively low boiling point, good volatility, and strong acidity, so it can catalyze many acid-catalyzed chemical reactions, and post-treatment is relatively easy and can be removed by vacuum distillation. In addition, trifluoroacetic acid can participate in oxidation reactions, reduction reactions, rearrangement reactions and deprotection groups.
Fourth, used as a test reagent, solvent, catalyst and for organic synthesis.
